Is CRC in HDD enough to protect data from corrupt?

Hello, I'm currently using onboard RAID 5 with 3 HDDs, but I feel it's slow, I want to change those to 1 HDD + 1 SSD, I know that every modern HDDs have built in CRC, but is it really enough to prevent data corruption without RAID? It's a personal desktop computer, maybe not as critical as "life-dependent" level, but I want to keep it very safe and stable. Thank you for any idea.

Oh if they are standalone then yea just go for it. I mean the thing you have to worry about the most is drive failure not so much corruption

Do you plan on using the SSD as a Cashe? Or do you plan on doing a RAID 1 or something?

Unless you do a Hybrid setup (were the SSD is more of a Cashe than anything) you don't get a whole lot of benifits.

Mixing HDD's and SSD's in ANY RAID will make it run as the slowest speed which in this case the SSD so that is point less.

You'd be better off getting a 4th HDD and setting up a RAID 10 if your Raid Card Supports it.

Thank you for your reply.
I plan to use them each as standalone disks, without any RAID or cache setup, that's why I ask this question.
